Of the four mentioned, I don't see Dr Carson as a candidate in 2016. He is an intelligent man and clearly conservative but he has never held elected office and I think the office needs a person with real governing experience. I prefer a governor, as they have real time experience in all of the areas the federal government does but on a state scale.
Rand Paul, like his father, is an isolationist. I prefer someone who is a little more engaged in the world, as the U.S. is still the leader of the world and the nation that others look to for support. Rand Paul does discourage speaking ill of other Republicans which is something the others should strive to do more often. Unifying the party is done through example of political leaders. We have to be a unified party to win in 2016.
